what is that smell ??!!?

I don't know where it's coming from but I know it's only around our building in TVA. ugh it's so gross! i really don't know what the smell is. I asked Joe and Sonya if they could smell what I was smelling and they were like "huh?!" Even when I took the trash this morning I asked one of my neighbors if it sometimes smells like this but fortunately for her she couldn't smell because her nose was stuffed. It's driving me crazy. Well it's a good thing i can vent to myself on here haha.
